Question

我在把营地添加到包括框架在内的html方面有问题。这里是我的法典;

    <?php
    session_start();
if (($_SESSION[ accesslevel ] != "normal") ||($_SESSION[ accesslevel ] != "admin" )) {
?>
    <meta http-equiv="refresh" content="0; url=./login.html">
    <?php}else {?>

<!DOCTYPE HTML>
<html lang="en">
<head>
<title>METU 3D Panaromic View</title>
<meta name="description" content="File Upload widget with multiple file selection, drag&amp;drop support, progress bar and preview images for jQuery.

它看不出是否在实验室,因此总是转向标识。如何在不提供框架的情况下处理。

感谢。

Answer 1

http://www.php.net/manual/en/Function.header.php“rel=“nofollow”header http://www.un.org/Depts/DGACM/index_french.htm

header( Location:login.html );

你们目前这样做的方式是,你冒着向客户发送内容的风险,即他们不应接触,而只是转头。

除此以外,我认为你的实际问题是“风海逻辑”,似乎你应当使用一种ool,而不是一种OR:

if (($_SESSION[ accesslevel ] != "normal") && ($_SESSION[ accesslevel ] != "admin" )) {

Answer 2

你在这里的条件是:

if (($_SESSION[ accesslevel ] != "normal") ||($_SESSION[ accesslevel ] != "admin" )) {

这两项条件中的一项是:<>途径是真实的——_SESSION[接入水平将永远不等同于“正常”,也不等于“行政”。 (可能与两者平等)。

也许意味着:

if (!($_SESSION[ accesslevel ] == "normal" || $_SESSION[ accesslevel ] != "admin")) {

Answer 3

I tried your code. Array $_SESSION is empty! According with php manual (session_start section), "The read callback will retrieve any existing session data (stored in a special serialized format) and will be unserialized and used to automatically populate the $_SESSION superglobal when the read callback returns the saved session data back to PHP session handling." So, if you don t have any previous session going on, it seems that array $_SESSION is never populated and any test you make on it will not give any usefull result.

Answer 4

<?php
session_start();
if (isset($_SESSION[ accesslevel ]) && !(($_SESSION[ accesslevel ] == "normal") || ($_SESSION[ accesslevel ] == "admin" ))) {
?>
